Tufflink™ 360° Link Clamp Double Acting Link Clamp
Double Acting Rotary Lug
- Available in 6 sizes: 600 lbs to 5,000 lbs capacities at 5,000 psi.
- Patented rotary lug feature delivers 360° of lever and/or body positioning.
- Maximum clamping force – minimal footprint.
- Top flange manifold mounted or standard plumbed.
- Independent body/lever adjustment simplifies manifold mount drill passage design or plumbing position and installation.
- Levers sold separately.
- Optional In-Port Flow Control is a meter-in device with reverse free flow check valve.
- Optional In-Port Sequence Valve is a sequencing device with reverse free flow check valve.
- Manifold fitting model no. 30-8711-20, adapter assembly and plugs are included with the clamp. Model 16-3228-00 and 13-3232-00 do not require the adapter assembly for manifold mounting.
- U.S. Patent No. 8,678,362.
- See Ultrasonic variant.
* Clamp capacities are listed at 5,000 psi maximum operating pressure with a standard length link clamp lever installed. Minimum operating pressure is 500 psi for double acting devices. The clamping force is adjustable by varying the hydraulic system pressure. Use of an extended length lever will result in a reduction of clamp force. See Clamping Force and Tables for the clamping force of various lever lengths and pressures. (Actual force will vary slightly due to mechanical inefficiencies, friction and/or return springs.)
** Equal to +/- 3° with standard lever.
*** To insure maximum service life and trouble-free operation, restrict fluid flow to the above flow ratings when clamping. If you are unable to measure flow rates, these devices should be positioned in no less than 1/2 second. These recommendations apply when using the standard lever. When using the optional extended lever or your custom lever, please restrict the flow rates to position the lever in no less than 1 second.
**** In-Port Valves require the use of manifold mount ports.
** Equal to +/- 3° with standard lever.

For proper sealing, mating surface must be flat within 0.003 with a maximum 63 µin Ra surface finish.
Levers are to be adjusted to within +/- 3° of nominal clamp angle to prevent premature failure.
For proper sealing, mating surface must be flat within 0.003 with a maximum 63 µin Ra surface finish.
